scholes25 0 Report post Posted August 12, 2004 (edited) Hi Goondu, I was hoping that my SR8300 has a high enough impedance rating to drive our new cans. That way I dun have to buy a new amp, save lots of money So, a big pretty please to anyone who has the information, do let me know. Thank You PS Short update on this set of cans, this is my 1st high end pair of cans, my other cans are the Philips HP890 and the Senn 497. TWO WORDS. NO CONTEST!!!!

Mackie 0 Report post Posted August 12, 2004 (edited) scholes25: Don't worry dude. I tested all the 650s via headphone socket of Marantz SA8260 sacd/cdp. Apparantely, this unit has a dedicated circuit board which drives the 650 to deafening loudness with decent sound quality when the vol pot is adjusted to 11 o'clock. I'm confident SR8300 has the same capability (if not better) as modern day hi-end AV amps also cater to cinematic experience via headphones. Behold the partially hidden pcb board with an op=amp at around 9 o'clock on picture. Edited August 12, 2004 by Mackie Share this post Link to post Share on other sites

Firefox 0 Report post Posted August 12, 2004 About 158 ohms impedance assuming it's a similar headphone circuit to the CD6000 series. Share this post Link to post Share on other sites
scholes25 0 Report post Posted August 13, 2004 Firefox, thanks for the info. Please pardon my ignorance again, but is 158ohms enough to drive a Senn HD650? Thanks again for all your replies. Share this post Link to post Share on other sites
Mackie 0 Report post Posted August 13, 2004 Given that your SR8300 is a high-end receiver, it should have all the required juice to power HD650. Remember to deactivate your surround modes when listening to music via cans. Then again, an amp will be in the offing once your demand on the 650 increases.

scholes25 0 Report post Posted August 13, 2004 THanks once again Mackie. I have been doing that. Disabling the surround effects and using pure stereo mode on my receiver. Mackie You have always been a great help to everyone in this forum. For all your help you have given to me and the forum, I SALUTE YOU!!! Share this post Link to post Share on other sites
Mackie 0 Report post Posted August 13, 2004 Don't stand on ceremony scholes. Thanks for the compliment. For the fun of it, sit thru a war movie with cans and U'll be pleasantly surprised by a different surround sound experience; one which will not pan as precisely as speakers but U'll enjoy the "resonance" of a flyby or firing of MG.

Interesting...... I would like to give my SR4300 a try with my grado SR80.. however, got a problem here...the headphone cables for the SR80 somehow is a little too short for me....

Mackie 0 Report post Posted August 16, 2004 I hate to dampen your excitement but U might find bass impact of movies on SR80 somewhat lean albeit tight and controlled. U could always purchase a Belden microphone cable from Robert at LHS and get him to terminate the plugs for U. Share this post Link to post Share on other sites
